Answer:
Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
Explanation:
Sensation helps us to detect changes in our physical environment.
Sensation occurs in three steps,
- Sensory receptors, these detect stimuli.
- Sensory stimuli are converted into electrical impulses to be decoded by the brain.
- Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.
Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
Internal energy is<span> the </span>energy<span> associated with the random, disordered motion of molecules. This energy </span><span>can not be transferred. whereas. </span>thermal energy<span> is the </span>energy<span> due to temperature </span>difference<span>. </span>
Thermal energy<span> is the </span>energy that comes due to temperature difference. It comes from heat generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.
The relationship between the heat, the internal energy and the thermal energy is the motion, whether of molecules (internal energy) or of particles (thermal energy).
Answer:
326.4 mC
Explanation:
The relationship between charge, capacitance and voltage in a capacitor is given by
where
C is the capacitance
Q is the charge
V is the voltage
In this problem, we have
C = 34 mF is the capacitance
V = 9.6 V is the voltage
Re-arranging the equation and substituting the numbers, we find the charge stored in the capacitor:
Answer:
2.25 kg
Explanation:
Length, L = 6 m
tension, T = 600 N
velocity, v = 40 m/s
The formula for the velocity is given by
where, μ is mass per unit length
μ = 0.375
m / L = 0.375
m = 0.375 x 6 = 2.25 kg
Thus, the mass of rope is 2.25 Kg.
Answer:
m = 1.31 kg
Explanation:
Given that,
The speed of duck, v = 9.1 m/s
The magnitude of momentum, p = 12 kg-m/s
We need to find the mass of the duck. We know that the momentum of an object is given by :
p = mv
Where
m is the mass of the duck
So, the mass of the duck is equal to 1.31 kg.
